Answer:
$181.19
Step-by-step explanation:
The coupon means you will pay 70% of the bill. The tax means you will pay 105.65% of the amount after the coupon is applied. Your final bill is ...
$245 × 0.70 × 1.0565 ≈ $181.19
_____
Your bill after the coupon is applied will be ...
bill - 0.30×bill = bill(1 - 0.30) = bill×0.70
The amount after tax is added is ...
charge + 0.0565×charge = charge(1 +0.0565) = charge×1.0565
Since the final bill is the product of these factors, the order of application does not matter. Conventionally, tax is applied last, so that accounting with the tax collection authority is properly maintained.
